SPECIFICATION forming part Of Letters Patent No. 593,808, dated November 16, 1897. Ap li ati fil d December 10, 1896- Serial No. 615,139. (No model.) I

To all whom it may concern:

Be it known that we, WILLIAM E. LIPPIN- COTT and OTTO E. C. I-IOMANN, citizens of the United States of America, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Motors, of which g the above-referred-to class that will be extremely simple in its construction, strong, durable, and effectual in its operation; furthermore, a motor that will be comparatively inexpensive to manufacture.

The invention has for its furtherobject to provide a reversing mechanism that may be easily operated and the direction of the rotation of the motor reversed.

The invention consistsin a rotary motor carrying one or more sets of pistons that are alternately opened and closed automatically at a predetermined point at each revolution of the motor. r

The invention further consists in providing the motor with air-tight packing, operating in conjunction with the valves, that leakage will be impossible.

The invention finally consists in the novel construction, combination, and arrangement of parts to be hereinafter more specifically described, and particularly pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like figures of reference indicate similar parts throughout the several views, in which 1 Figure 1 is a side elevation of our motor. Fig. 2 is a vertical longitudinal sectional view showingv all parts in position. Fig. 3 is a top plan view. Fig. 4 is a horizontal sectional View taken on the line X X of Fig. 1. Fig. 5 is a transverse sectional View, partly broken away, taken on the line Y Y of Fig. 1. Fig. 6 is a transverse vertical sectional view taken on the line Z Z of Fig. 1. Fig. 7 is a side view of one of the rocker-shafts. Fig. 8 is a side view of the feed and exhaust valves. Fig. 9 is a plan view of the packing-gland of feed and exhaust valve. Fig. 10 is a horizontal longitudinal sectional view of a portion of the motor, showing the springs engaging the packing.

Referring now to the drawings by referen cefigures, 1 denotes the outer rim of the cylinder, 2 the sides, and 3 3 the supporting-legs carried by the rim, said sides being centrally apertured to receive the driving-shaft. (Not shown.) The sides 2 2 are securely fastened together by means of bolts or rivets 4. 4, said rim being provided with circumferential grooves 5 5 on each side thereof to receive the sides 2 2, said grooves forming a packing-seat for the packing 6. The rim 1 is further provided with circumferential grooves 7 7 outside of the grooves 5 5, which receive the ballbearings 8 8, and a packing 9, on which rest the circumferential flanges 10 10 of the sides 2 2. The rim is further provided with an aperture to insert the ball-bearings in the groove 7, said aperture being closed by a thumb-screw 11.

The sides 2 2 are provided on their inner faces with raised circular portions 12 12, which abut against each other, thus forming a circular cylinder 14 between the outer rim of the raised portions and the inner face of the rim 1. Within the raised portions 12 12 are swiveled, by means of bolts 15, the rockers 16 16, said portions 12 12 being cored sufficiently to permit the free working of the rockers, which are provided with shaft ends 17 17, engaging in the recesses or cored portions 18 18 of the pistons 19 19, operating in the slides 20 20 in the cylinder-base and raised portions 12 12. cylinder the rim .1 is provided with a block 21, having inclined faces 22 22 and being grooved to receive a packing 23, and to the head 24: of the rim is securely fastened a bellplate 25, provided with an exhaust-port 26, the openings 27 27 a of which extend through the head 24 and slide-valve into the cylinder 14 on each side of the block 21.

At the upper portion of the The inlet-port 28 is arranged at the side of the bell-plate 25, the openings 29 and 29 of said port extending through the slide-valve into the cylinder 14, through the head 24 and block 21, and between the exhaust-openings 27 27.

The top of the head 2 f is provided with a groove 30, which receives the feed and exhaust valve 31, to which is attached the stem 32, forming the reverse-rod, provided with a packing-gland A packing 3i in the bellplate closes the openings and prevents the air from passing to the exhaust from the inlet. The block 21 is provided with a recessed or cored portion 35, in which is secured a packing 36, held in contact with the outer rim of the raised portion at all times by springs 37 37 in the block 21.

For the purpose of illustration we will assume that the parts have all been secured in their respective positions and the inlet-port connected to the supply-pipe. As the air, steam, water, or other motive power being employed passes into the cylinder 14 through the port 29 it passes around the cylinder until it engages the piston 19, and the pressure thus obtained carries the sides 2 2 around until the piston then in engagement is forced past the exhaust-port 27, which permits the air or other motive power to escape as the piston thus operated rides on the inclined face of the block 21. The rockerlG will force the twin piston outward in position to receive the motive power from the inlet-port. When reversed by means of the reverse rod or stem 32, the inlet-port 29 and the exhaust-port 27 are closed and the inlet-port 29 and exhaustport 27 are opened, thus operating the motor in the reverse direction, the operation of the pistons being substantially the same with the sides moving in the opposite direction.

It will be noted that as manyinlet and outlet ports may be arranged in the motor as may be desired, and by actual practice we have found that the construction as heretofore set forth and described will successfully overcome the various objections that have been found in machines of this nature.

It will be readily apparentalso that this motor may be modified in the details of construction in many parts without departing from the general spirit of our invention.

Having fully described our invention,what we claim as new, and desire to secure by Letters Patent, is-

1. In a rotary motor, two pistons having an endwise movement, combined with a rocking lever which is connected directly to the inner end of each piston, whereby the movement of one piston operates the other in an opposite direction; and the frame of the engine, having an abutment to operate the pistons, substantially as set forth.

2. In a rotary motor, an inclosing case, and a rotary cylinder having radial grooves made therein, and a suitable opening between the grooves, combined with the two endwise-movin g pistons placed in the grooves, and a rocking lever pivoted between the two pistons, and loosely connected directly to them both, whereby when the rotation of the cylinder brings the forward piston in contact with the abutment, and it is forced backward into its groove, the other piston will be forced outwardly, substantially as specified.

3. A grooved outer ring, a central cylinder, and two sides secured to the cylinder and provided with flanges to fit in the grooves in the ring, combined with two pistons having an endwise movement, a rocking lever which is connected directly to the inner end of each piston, the outer ring being provided with an.

abutment to operate the pistons, substantially as specified.

In testimony whereof we affix our signatures in presence of two witnesses.
